RUBELLA AB (IGG), IMMUNE STATUS

Clinical Significance

Rubella Antibody (IgG), Immune Status - Rubella is an acute exanthematous viral infection of children and adults. Rash, fever and lymphadenopathy characterize the illness. While many infections are subclinical, this virus has the potential to cause fetal infection with resultant birth defects.
Diagnosis of a Rubella infection is best made serologically. In the absence of a current or recent infection, a demonstration of specific IgG on a serum sample is evidence of immunity to Rubella.
